https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D213621 --- Comment #7 from Adrian Chadd <adrian@freebsd.org> --- God damnit, okay. So it /looks/ like a single bit corruption of the RSC, wh= ich causes the AES-CCM code to consider everything afterwards to be a replay attack. ie: Adrians-MacBook-Pro:~ adrian$ perl -e 'printf "%x\n", 3407656;' 33ff28 Adrians-MacBook-Pro:~ adrian$ perl -e 'printf "%x\n", 2150891303;' 8033ff27 Those are from your AES-CCM replay logs. I would've thought that a single bit error would've been caught by the MAC CRC/FCS. -adrian --=20 You are receiving this mail because: You are the assignee for the bug.=
